Deuteronomy 8:3

3. He humbled thee,… and fed thee with manna Comp. Exodus 16:16. Jehovah had shown them their dependence on him, and then in their extremity he provides an abundant supply for their bodily wants.

By every word that proceedeth out of the mouth of The Lord More literally rendered, on every utterance of the mouth of Jehovah. In this verse the word bread is employed to include all the ordinary provision for sustaining human life. When Jesus quotes this passage in reply to the tempter (Matthew 4:4; Luke 4:4) he means to say that life can be sustained by extraordinary means. God can employ other means and methods. Life can be sustained by other provision. The Saviour, as he sat by Jacob’s well, said to his disciples, “I have meat to eat that ye know not of.” John 4:32.
